hasCorrectLength static method

bool hasCorrectLength(Uint8List datagram)

Checks if the datagram has the correct length for a message.

A message is considered to have the correct length if it is either an empty signed message (containing only header and signature) or a signed message with a payload of at least sealLength bytes.

datagram The datagram to check.

Returns true if the datagram has the correct length, false otherwise.

Implementation

static bool hasCorrectLength(Uint8List datagram) =>
    datagram.length == emptySignedMessageLength ||
    datagram.length > emptySignedMessageLength + sealLength;
